Internet of things (IoT) is most rapidly increasing technology in the modern world and this technology is bringing revolution in the field of information systems and computing technologies.The internet of things (IOT) is the network of physical objects or things embedded with electronic software sensors and networks connectivity, which enables these objects to collect and exchange data link. Information is a great way to reduce waste and increase coherence and that’s really what the IOT provides.The history of internet of things (IOT) started in 1999 the IOT gets a name kevin ashton coins the term “INTERNET OF THINGS” and establishes MIT’s Auto- ID center a global research network of academic laboratories focused on RFID and IOT.
Internet of thing is a technology in which object of the real world communicate with each other the internet of things promises a world in which physical objects of all kinds from household systems to healthcare monitors are enabled to collect and exchange the data IOT could “TURN THE WORLD INTO DATA” that could be used to make macro determination on research utilization. In 2020, things or gadgets connected to the internet would be 20 billion which shows the revolutionary increment in the field of internet of things (IoT).
Internet of thing is a technology in which object of the real world communicate with each other. IOT also sometimes referred to as an INTERNET OF EVERYTHING (IOE) consist of all web-enabled devices that collect send and act on data they obtain from their surrounding environment using embedded sensors processors and communication hard ward. These devices often called “CONNECTED OR SMART DEVICES” can sometimes talk to other related devices a process called MACHINE TO MACHINE (M2M) communication and act on the information they get from one and other. Humans can communicate with gadgets to set them up, give them instructions or access the data, but the device do most of the work on their own without human interposition. Their actuality has been made possible by all the tiny components, that are available these days, as well as the always online nature of our home.
The internet of things promises a world in which physical objects all kinds from household systems to healthcare monitors are enabled to collect and exchange the data .The idea is that not only your computer and your smartphone can talk to each other, but also all the things around you. From connected homes and cities to connected cars and machines to devices that track an individual’s behavior and use the data collected for new kind of services.To the public, IoT currently appears to be a mixture of smart home applications, wearable’s and an industrial IoT component. But actually it has the potential to have a much wider reach. When the connected world becomes reality, the Internet of Things will transform nearly all major segments – from homes to hospitals and from cars to cities.
IOT also have general and advance components. So these components react on our daily life.First of all, we need things we want to connect. It can be sensor, actuators, and robots, whatever can be connected. The most developed technology is about sensor field. There are many different sensors are available today. Whether you want to measure temperature, humidity, light, noise, pollution, pressure, torsion, tension, acceleration, position, images, magnetic fields, electric fields, etc., there is a large array of sensors to choose from. They were large, bulky and strong hungry.Today they are hidden and efficient, while maintaining high-precision health. The technology field of actuators and robots, whether large or small, is still evolving. But even so, there is a monetarism trend and hopefully by 2020 Internet stuff will have a healthy mixture of insight and robot-measuring sensors. If you later select the sensor or the actuator, you will need to be confidently connected to the Internet.
According to the RFID Journal the technology is “any method of identifying unique items using radio waves. Usually, a reader interacting with a transmitter who has digital information in microchips. This technology depends on the close range, in order to keep internal stock control, storage lists trust RFID. For exampleNFC Communication technology based on radio waves at 13.56 MHz frequency Short range (<= 10 cm theoretical, 1-4 cm typical) - Low speed (106 / 216 / 414 kbps) => 13-50KBytes per sec Low friction setup (no discovery, no pairing) Setup-time < 0.1 Sec . Communication roles:Master Device: NFC Initiator (starts communication, typically a device) Slave Device: NFC Target (passive tag or device)The Internet of Things promises a world in which physical objects of all kinds — from household systems to health monitors — are able to collect and exchange data. It’s an attractive prospect, enabling remarkable efficiency and productivity, less data re-entry, easier control, and the many benefits of data analytics.
But there are challenges in implementing the internet of things. For example How can you ensure network connection for an object? How Affiliate Items Know User Intention? What about security? And how do you add non-authorized things that do not access the nearby Internet?These all questions answer given by NFCNFC. enabled mobile phones contain NFC tags which are useful in retrieving information from other NFC enabled mobile phones. The integrity of the data stored in these tags is maintained using digital signatures. However there is no guarantee on the authenticity of these tags. These tags can be replaced with illegitimate tags by the attacker leading to security breaches.
